I found an implementation error in your latest release:
DWORD CXTPSystemVersion::GetComCtlVersion() const { static DWORD dwVersion = 0; if (0 != dwVersion) { dwVersion = CXTPModuleHandle(_T("comctl32.dll")).GetVersion(); if (0 == dwVersion) dwVersion = MAKELONG(0, 4); // Old ComCtl32 had version 4.0 } return dwVersion; } the correct implementation would be: DWORD CXTPSystemVersion::GetComCtlVersion() const { static DWORD dwVersion = 0; if (0 == dwVersion) { dwVersion = CXTPModuleHandle(_T("comctl32.dll")).GetVersion(); if (0 == dwVersion) dwVersion = MAKELONG(0, 4); // Old ComCtl32 had version 4.0 } return dwVersion; } One effect is that some image lists do not support the alpha channel of icons.

Hello Marcus,
We have fixed this yesterday. Other customer on support reported about this bug. I have investigated what it can affect on: - BalloonStyle tooltips not supported. CXTPToolTipContext::IsBalloonStyleSupported() - alpha icons handling CXTPImageManagerResource::Add() -> CXTPImageManager::IsAlphaIconsImageListSupported() - inflate ReBar for 4 px in CXTPReBarBase::_AddBar() - CXTPWinThemeWrapper::IsAppThemeReady() can return FALSE instead of TRUE (used in very many places); - CXTPTaskDialogProgressCtrl drawing - using user defined colors in CXTPTreeBase::GetTreeBackColor() and CXTPTreeBase::GetTreeTextColor() - wrong return value in CXTPAuxData::GetComCtlVersion() - wrong return value in CXTPSkinManager::IsComCtlV6() -> CXTPSkinObjectToolBar::IsAlphaImageList()
Thank you. Oleksandr Lebed |

This is a silly and serious bug. You need to release a new update as soon as possible. When is next update expected?

In Version 18 it is not possible anymore to use Alpha-Icons from picture-sources...
For example (comparison: Version 15 and Version 18):   As you can see the Alpha-Icons are distorted!!!  Example Source-Code: SourceCode_BUG-Example.zip |

We pulled 18.0.1 and just tracked down the same bug in the code and that led me here via a search. Is this fixed or not? If so, what version?
